Sequences, Time Series and Prediction: C4W1_Lab2

[fatihah]

When creating a post, please ad hi i just wanna ask at this ungraded lab, at the smoothing section:
to find the diff moving avg + smooth from the past:

1. when slicing why split_time -370 not 365?
2. then split time -370:359,11 359 is the current year? since we gave to 370? so how we want to decide the windows time ? why is it 11 is it depend on our project?

Hi @fatihah You also needed to move your query to the right section by using the edit pen option, for now I have moved it to the right category for response from the course mentors. the split time is 370 as the slicing is related to the series (i.e. period and noise level of 5) and not only period. If you check the generate synthetic data, the forecast is a seasonal trend of 365 steps but some noise is added as the real world data often has some noise. In numerical analysis, noise is genera…

Feel free to ask if more doubts.
